DC Generators When two D.C. generators are running in parallel an equalizer bar is used To increase the generated e.m.f. So that the two identical machines will pass approximately equal currents to the load To reduce the combined effect of armature reaction of both the machines To increase the series flux To increase the generated e.m.f. So that the two identical machines will pass approximately equal currents to the load To reduce the combined effect of armature reaction of both the machines To increase the series flux ANSWER DOWNLOAD EXAMIANS APP
